ENGINE MOUNTING.

Application filed February 11, 1924.

T0 aZZ w /1 am it may concern.

Be it known that I, TOMMY SrmYooK, a citizen of the United States, residing at Tyrone, in the county of Anderson and State of Kentucky, have invented new and useful Improvements in Engine Mountings, of which the following is a specification.

Rowboats and similar small watercraft are often propelled by a motor secured on the stern thereof. The operation of the motor occasions vibration to such extent that the occupants of the boat are rendered uncomfortable, also frequently inflicting injury to the boat and impairing the power of the propeller. It is, therefore, the object of this invention to provide a means for mounting propeller actuated motors on a boat which will overcome such vibrations.

A further object is the production of a mount for marine engines on small watercraft that shall be of a simple construction, cheaply manufactured, readily installed, and which will effectively prevent the engine imparting undue vibration to the craft.

The drawings, which accompany and form part of this application, illustrate a satisfactory embodiment of my improvement reduced to practice, and wherein Figure 1 is a rear elevation of a watercraft embodying the improvement.

Figure 2 is a side elevation thereof.

Figure 3 is a top plan view thereof.

Figure l is a sectional view on the line et-d of Figure 3.

In the drawings, the numeral 1 designates a sullicient portion of a stern of a small watercraft to illustrate the application of my improvement thereon. The rear seat of the craft is indicated by the numeral 2. Either hinged directly to the seat 2 or to a board secured on said seat there is a plate 3 that constitutes one of the elements of my improvement. The hinged connection for the plate is indicated by the numeral 4.

Passing through suitable openings adjacent to the outer end of the plate 3 there are bolt members 5. On these bolts there are screwed nuts 6. The nuts 6 contact with washers 7. On each of the bolts there is an inner sprin 8 and an outer spring 8. On each of the bolts there is an ear disposed be- Serial No. 692,115.

tween the springs 8 and 8. The ear 10 is formed on one end of an angularly disposed rod 11. The second end of the rod is also disposed at an angle as indicated by the numeral 12. The ends 12 of the respective rods 11 are provided with openings 13, and through these openings there are passed the shanks of bolts 14-. The bolts also pass through the seat board 2 and have screwed thereon nuts 15.

The motor 16 for the propeller is firmly secured to the outer face of the plate The plate is sustained normally in an upright position, or at a right angle with respect to the seat 2 by the brace rods 11 and by the springs 8 and S which are disposed between the outer angle ends 10 of the said rods 11, the plate 3 and the washer 7 Thus the plate is yieldably connected to the craft 1, the out ward yielding of the plate, however, being restricted by the said springs 8 and 8. In this manner, vibration which the bolt 5 would. be subjected to were the springs 8 and 8 dispensed with is effectively overcome. The swinging movement of the plate 3 is likewise, limited by the compression of either of the springs between the end 10, the plate 3 or the end 10 of the rod and the washer 7.

Having described the invention, I claim 2- 1. A means for mounting the motor of a propeller on a small watercraft, comprising a plate hingedly secured to the rear seat of the craft, and on whose outer face the motor is supported, angle brace rods removably secured to the seatand directed toward the plate, guide means on the plate for the rods, means holding the rods on said guide means, and resilient cushioning means on the guide means in engagement with the rods.

2. A means for supporting the motor of a propeller on a small watercraft, comprising a plate hingedly secured to the rear seat of the craft and on whose outer face the motor is attached, bolts on the corners of the plate extending inwardly therefrom, nuts engagingthe bolts, spaced washers on the bolts, helical spring between said washers, brace rods removably secured to the seat having angle ends provided with eyes receiving the bolts therethrough, and the eye ends of each of the brace rods being disposed between the engaging said bolts angle brace rods secured outer Washers and the nuts for the bolts. to the craft and having upper angle ends 3. A means for supporting the motor of a through which the bolts pass, and helical 10 propeller on a small watercraft, comprising springs on the bolts between the said end of 5 a plate hingedly secured to the rear seat of the rods, the board and the washer.

the craft and on which the motor is secured, In testimony whereof I aflix my signature. bolts passing through the plates and nuts TOMMY SI-IRYOCK.
